Steve,
#1.
since you know 3,4,5 is a pythagorean triple, so is any multiple of those numbers. Looks like 33,44,55 to me.
#2
just multiply 3,4,5 by 4.
#3.
since the diagonal of a 90' square is 90√2, pick the only answer greater than 90. (you might also check it to be sure it fits)
#4.
at 9:00 you have a right triangle with legs 1.2 and 1.5. just figure the hypotenuse. (looks like another 3,4,5 triangle to me!)
#5.
to avoid working with big numbers, scale down by a factor of 6. Now you have a side of 6 and a hypotenuse of 7.
4936 = 13, so 6*√13 = 21.6

Steve,
Oops. #4 isn't 3,4,5. It's 4,5,√41, scaled by .3. SO, .3√41 = 1.9
